United States Patent 3,335,729 CIGARETTE FILTERMEANS Andrew L. Ice, Sacramento, Calif. (7540 Lone Oak Drive, Citrus Heights, Calif. 95610) Filed Mar. 31, 1964, Ser. No. 356,097 1 Claim. (Cl. 131-10.5)

ABSTRACT OF THE DISCLOSURE A cigarette filter which comprises a centrally apertured disc disposed adjacent the cigarette tobacco closely covered by an elongate ribbon baffle member overlying the disc and the aperture such that the smoke is laterally displaced by the baffle, said disc and baffle being secured on the end of a cigarette by an annular mouthpiece.

This invention relates to tobacco filters, and more particularly to cigarette filters for the removal of tobacco tars and other deleterious substances from the smoke stream of a cigarette and the like before entry to the mouth of the smoker without substantially decreasing the pleasurable taste of the tobacco used in the cigarette.

To solve the problems of accumulation of tars, and deleterious substances ordinarily found in tobacco smoke, the instant invention provides a simple, cheap and dependable means of substantially eliminating such substances from the smoke stream before entry into the smokers mouth.

A primary object of this invention is to provide an efficient and simple filter means of substantially eliminating tars and deleterious substances from tobacco smoke still preserving the natural tobacco taste of the cigarette or the like.

Another object of this invention is to provide a simple filter means for trapping out or accumulating of the tars and such deleterious substances on the filter means before entry into a smokers mouth.

A further object of the invention is to provide a smoke filter means of suitable transverse and longitudinal crosssections of simple filter materials which also cooperatively uses an auxiliary filter bafiie of tobacco particles to substantially accumulate or inhibit tars or other deleterious ingredients of the combustion smoke stream of the cigarette from passing through the month end of a cigarette or the like.

With the foregoing and other objects in view which will appear as the description proceeds, the invention comprises certain novel details of construction and com- 'binati-on of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts therein without departing from the spirit and scope of the invention as claimed.

In the drawing:

FIGURE 1 is a perspective longitudinal view of a conventional filter cigarette showing the location of one embodiment of the new filter means of the instant invention installed therein adjacent to the mouth piece end of the same;

FIGURE 2 is an enlarged partial longitudinal sectional view taken substantially on lines 2-2 of FIGURE 1, in the direction of the arrows;

FIGURE 3 is a transverse sectional view taken sub stantially on lines 33 in the direction of the arrows;

FIGURE 4 is a perspective view of the new apertured disc bafile and tar trap baffle means of the above embodiment of the new filter means before assembly in a cigarette;

FIGURE 5 is a developed view of the separated apertured disc baffle and tar trap baffie means therefor, before 3,335,729 Patented Aug. 15, 1967 positioning of the filter means in a transverse position within a conventional cigarette;

FIGURE 6 is a partial longitudinal sectional view of a second embodiment of the present invention, in which an apertured disc baffle means and auxiliary filter of small tobacco particles are respectively positioned in spaced relationship ahead of the conventional cigarette filter means; and

FIGURE 7 is a partial longitudinal sectional view of a third embodiment of the invention in which the apertured disc baffle filter means of the present invention is placed within a mouthpiece ahead of a conventional filter, which mouthpiece is adapted to be placed over the mouth end of a conventional cigarette.

Like reference numerals represent like parts in the different views of the drawing.

Referring to the drawing, one embodiment of the invention comprises a disc bafile means 10 and a tar trap bafile means 12 placed in the mouth end of a conventional cigarette 14 over which is placed a mouth piece 16 which contains a conventional cigarette filter 18 Bafile means 10 contains therein a central aperture means 20 to restrict the smoke stream in cross-section using an orifice effect of potential and kinetic energies of gaseous smoke flow therethr-ough to stop and trap tars or deleterious ingredients therein upon a further background tar trap bafile means such as bafile means 12, the latter being slightly spaced from the downstream side of the disc baffie, as seen in FIG. 2, functions both to trap tars from the smoke emerging from aperture 20 and to force the smoke in a lateral direction where it emerges into an air space for expansion and cooling before being finally filtered by a conventional filter 18.

In use, the tar trap baflie means 12 is folded at broken lines a and b as shown in FIGURES 4 and 5 to be folded over the peripheral edges and aperture means 20 of bafiie means 10, before assembly in a conventional cigarette means 14, as best shown in FIGURE 2.

Referring to the second modification of this invention, as shown by FIGURE 6, filter trap means 12 of FIGURE 2, has been omitted in favor of a particled tobacco filter tar trap means 24 placed between orifice baffie means 10a having orifice 20a and conventional filter means 18a of cigarette means 14a having on its end portion a mouthpiece means 16a, containing therein a portion of the particled tobacco filter means 24. This filter arrangement is unique in that it gives a somewhat stronger tobacco taste and warmer smoke than obtained in the inventive filter modification of FIGURES 1 and 2, which resultant smoke and taste is more pleasurable to the more demanding and varied taste requirements of a cigarette smoker than a cigarette having only a conventional filter in the month end thereof.

In the third modification of this invention, as shown by FIGURE 7, the tar trap means of the two above modifications of the invention has been omitted in favor of the disc means 10b having aperture means 201) in combination with conventional filter means 18b, for the smoker who desires a still hotter smoke. The cigarette 1412 has the mouthpiece 16b securing the conventional filter means 18b and the apertured disc means 10b thereto to provide a more pleasurable taste to a cigarette smoker who desires better filter protection than that usually afforded by the conventional filter means 1812 alone.

It is to be understood that the filter means of this invention may be used either as the sole filter means or as an auxiliary filter means in a conventional cigar, cigarette and the like, if desired.

From the foregoing, it will now be seen that there is herein provided an improved type of cigarette filter means for a cigarette and the like which accomplishes all the objects of this invention, and others, including many advantages of great practical utility and commercial importance.

As many embodiments may be made of the embodiments of this inventive concept, as desired by those skilled in the art without departing therefrom, and therefore, it is to be understood that all matter herein disclosed is to be interpreted merely as illustrative and not in a limiting sense.

I claim:

A cigarette and filter structure comprising a wrapped cylindrical tobacco charge and so fitted within a cylindrical tip element which houses a filter means to define an air space between the downstream end of the tobacco and the said filter means, a disc bafile of a diameter substantially equal to that of the inside of the wrapper and provided with a central smoke restricting aperture therein, the said bafile being disposed in contact with the downstream end of the tobacco charge, and a second U-shaped bafile element of a width less than that of the disc, the said 20 U-shaped bafiie having its base almost in contact with the downstream side of the disc baffle and its legs disposed between the edge of the disc and the tobacco wrapper, the base of the said U-shaped bafiie functioning to trap tars and to direct the smoke in a lateral path between the two baffies into the air space and thence through the filter into the mouth of the user.
